Popular Logitech Trackball "Ergo" ✨ This is the popular Ergo trackball mouse purchased from Logitech's official online store. It's designed with ergonomics in mind to reduce strain on your arms and wrists, providing comfortable operation. Opened after purchase, and only connected to a computer once! I'm selling it because it didn't fit my hand size. ・There are no noticeable scratches or marks, and it's in very clean condition. ・It has been carefully stored. ・All accessories are included (USB receiver). ✨ A great item for trackball enthusiasts and those who work for long hours. Purchased in February 2025 for 17,800 yen. I am a non-smoking woman. Don't miss this opportunity! - Model Name: MX ERGO - Brand: logicool - Connection Type: Wireless - Trackball Position: Right-handed Thank you for looking. You can purchase it immediately.
